3. 用作名詞,表示主動給予或提供某物,其后通常接 of 短語或不定式。如:

Thank you for your offer of help [to help]. 謝謝你愿意提供幫助。

He promised to make an offer of support (food). 他答應(yīng)愿給予支持(食物)

用作名詞,也可表示“出價”。如:

I’ve had an offer of $2000 for the piano. 有人已出兩千美元買這部鋼琴。

 

office n.

1. 表示“辦公室”、“辦公機(jī)構(gòu)”。若表示去辦公室上班,其前通常要用冠詞,雖然有時也省去,但很少見。如:

I don’t have to go to the office on Sundays. 星期日我不必去辦公室上班。

You didn’t go to (the) office today? 你今天沒去辦公?

2. 表示“公職”、“職務(wù)”、“職責(zé)”等,通常為可數(shù)名詞。如:

He has a very high office in the Government. 他在政府里擔(dān)任很高的職務(wù)。

Many offices in France could be bought. 在法國有許多職務(wù)可以用錢買到。

注:在某些短語中,可是不可數(shù)的。如:in office(執(zhí)政,當(dāng)權(quán))out of office(不執(zhí)政,不當(dāng)權(quán))take office(就職,上任)come

into office(上任,就職)leave office(離職)等。

 

often adv.

1. 表示“經(jīng)常”,通常放在行為動詞之前,特殊動詞(助動詞、情態(tài)動詞以及動詞 be)之后。如:

He was often late for class. 他上課經(jīng)常遲到。

He often goes out with her. 他經(jīng)常同她一起出去。

The boys have often been there. 孩子們經(jīng)常去那兒。

有時為了強(qiáng)調(diào),也可放在特殊動詞之前,甚至句首或句末。如:

He was often ill. /He often was ill. 他經(jīng)常生病。

He often writes to me. /He writes to me often. 他經(jīng)常給我寫信。

若受副詞修飾(加強(qiáng)語氣或強(qiáng)調(diào)),也通常位于句末或句首。如:

We go to the cinema quite [very] often. / Very [Quite]

often we go to the cinema. 我們經(jīng)常去看電影。

2. 用于 as often as, 起連詞作用,相當(dāng)于whenever, 意為“每當(dāng)”。如:

As often as I tried to ring him, the line was engaged. 每次我給他打電話都占線。

 

once adv. & conj.

1. 用作副詞,表示“一次”,是頻度狀語,通常放在句末;表示“曾經(jīng)”、“一度”,是表示不確定時間的副詞,通常放在行為動詞之前,特殊動詞(助動詞、情態(tài)動詞、動詞 be)之后,有時也可放在句首。如:

I’ll help you once but then you must do it by yourself. 我只幫你一次,但以后你就得自己做了。

This novel was once very popular but nobody reads it today. 這本小說曾經(jīng)很受歡迎,但現(xiàn)在沒有人讀了。

注:表示“一次”的 once 還經(jīng)常與 a, every 等連用。如:

We have a meeting once a week. 我們每周開會一次。

He goes home once every six months. 他每半年回家一次。

2. 用作連詞,引導(dǎo)時間狀語從句,注意從句要用現(xiàn)在時表示將來意義。如:

Once you begin, you must continue. 你一旦開始,就必須進(jìn)行下去。

Once you talk to him, you’ll know he’s a good person. 你只要同他談?wù)劊憔蜁浪莻好人。

所引導(dǎo)從句的主語若與主句主語一致,有時也可用其省略結(jié)構(gòu),被省略部分通常(并不總是)包括有動詞 be。如:

Once (it is) printed, the book will be very popular. 一旦出版,這本書會大受歡迎。

Once having made a promise, you should keep it. 你一旦許下諾言,就該遵守。

3. 比較 at once all at once: 前者表示“馬上”或“同時”;后者表示“突然”。如:

Come here at once. 馬上過來。

Don’t all speak at once. 不要一起說。

All at once we heard a loud noise. 突然我們聽到一聲巨響。
